Lafferty scored 11 goals in 34 appearances as Palermo were crowned Serie B champions in 2013-14 and the former Burnley and Rangers forward is excited at the prospect of returning to English football.

He told the club's official website: "Norwich is a team that wants to get promoted back to the Premier League at the first opportunity so I'm excited to come here and start playing football for a team like this.

"I've played in the Championship before and I've played against Norwich and things I noticed about the club were the fans and the football they played.

"Speaking to the gaffer [Neil Adams], everything he said and everything he wants me to do, it's good to have someone like that believing in me.
